VIDEO: Deputy dragged by intoxicated driver, suspect charged

Newly released dash-cam footage shows a Williamson County Sheriff's Office deputy getting dragged by a vehicle during a traffic stop.

It happened around 3 a.m. on Wednesday at the intersection of the 45 toll road and CR 172.

Sheriff Robert Chody says the deputy made the traffic stop after she observed the suspect, identified as Jonathan Nunnally, sit through an entire traffic light cycle.

Chody says Nunnally appeared to be passed out, and when the deputy opened the car door, he awoke and took his foot off the brake pedal slightly, causing the car to roll.

The deputy took the suspect's keys and place them on top of the car before asking for his license and registration. That's when Sheriff Chody says the suspect pulled out a second set of keys, which he was able to quickly get into the ignition and drive away.

As the car was speeding away, the deputy -- who has only been on the street for one month -- was able to slam the car into park and stun the suspect with a Taser, just as backup arrived to assist her.

According to Sheriff Chody, Nunnally was also in possession of marijuana and cough syrup. He's been booked in the Williamson County Jail, charged with aggravated assault against a public servant.

The deputy, who has not yet been identified, did not suffer any major injuries.
